Your favourite 'S' names for boys?

I'm trying to come up with some great boys' names for a friend who would like to honour her grandmother, Susan. She's Jewish, and although not particularly religious (so they don't have to be Hebrew names or anything, in fact she seems to quite like European-feeling names) it's apparently traditional to honour deceased relatives by choosing a name beginning with the same letter. So far she sort of likes Sam (but isn't sure about Sam by itself, and doesn't like Samuel because of the "mule" sound, she says).

So, what are your favourite boys' names which begin with S? She'd also be willing to consider names with the same meaning, but I haven't found any boys' names which share Susan's meaning (lily).
